No you don't. You would not do your suggestion if you did. How am i supposed 
to help nokia debug that problem with nepomuk not build? How am i supposed to 
find and fix the problem myself? Reonfigure and rebuild kdelibs all the time? 
Complete with cleaning out my installation area whenever i want to rebuild 
kdebase-runtime or kdepim?

For this cases macro_optional_find_package is made. Exclude a dependency that 
is found from the build. Making it possible to test different configurations of 
a build without going through the hoops to hide some dependecies from cmake.

You are right. I meant to say with the last paragraph this mail is not about 
this and i don't want to dicuss that here. But on a second reading that came 
not through. I naturally leave the decision about that to the kdepim people.
